Connection sets

Connection sets for stainless steel corrugated pipes provide all necessary components for secure and leak-free pipe connections. These sets are designed for use with IVAR.SITE-TR and similar systems, commonly found in heating, plumbing and solar applications. They include sealing washers, log rings, nuts and pressing heads in standard sizes such as 12mm (1/2"), 16mm (3/4") and 20mm (1").

Each set is tailored to specific installation needs, with variants for water, solar and production environments. The materials and design ensure compatibility with stainless steel bellows and maintain integrity under operational temperatures up to 370°C for solar applications.

How to choose

• Select the correct size (e.g. 12mm, 16mm or 20mm) based on the pipe diameter and thread type (metric or imperial).
• Choose the appropriate set type (e.g. IVAR.SITE-MA for nuts, IVAR.SITE-KR for log rings) depending on the required component.
• Match the set to the system type (water, solar or production) to ensure material and temperature compatibility.

Frequently asked questions

What components are included in a full connection set?
A full set typically includes 20 nuts, 20 log rings and 20 sealing washers, suitable for assembling multiple connections.

Can I use a solar-rated sealing washer for water systems?
Yes, solar-rated washers (e.g. IVAR.OMNIA SO) are suitable for water systems but water-rated washers are not recommended for solar due to temperature limitations.
